Arsenal, Tottenham Hotspur Chelsea and Liverpool have all received a massive boost in the race to sign Gelson Martins this summer.

The Portugal winger is not only currently at the World Cup in Russia - where he's made just one substitute appearance for the Euro 2016 winners - but he is also in the middle of cancelling his contract with Sporting CP.

Following a tempestuous end to the season for the Portuguese club, seven of their players looked to terminate their contracts following an altercation with fans ahead of a cup final appearance.

50 masked fans attacked players and staff in May following the side's failure to qualify for the Champions League and now Martins, alongside William Carvalho, Bruno Fernandes, Ruben Ribeiro, Bas Dost and Daniel Podence could be available for free this summer.

In the past the figure to prise Martins from Sporting is though to have been as high as €60m, while Arsenal are rumoured to have had a £26m bid rejected.

With 13 goals and 13 assists to his name last season, Martins would be a strong addition to the Gunners squad as he would provide a goal threat from the wide areas that has been missing since Alexis Sanchez and Theo Walcott left in January.
